Why and What

The MPE 2468 Powerboard allows you to buy boards that can be
used as the CPU heart of a product with your own custom I/O. The
board provides plenty of I/O pins on connectors at the edges of
the board. You can fit your own connectors, whether they be 0.1"
pitch strips or stacking connectors (PC104 stacking or even
gold-plated Samtec connectors). There are mounting holes for
pillars. You can concentrate on the I/O for your product.
